Isilinganiso Senzuzo Yezindleko	Kuyonga kakhulu amapayipi angagugi aphakathi nendawo kuya phezulu.	Ukuqina okuphezulu kanye nokuwohloka kokushisa okungapheli ezindaweni ezinzima.

2. Izici Zobunjiniyela Zezindawo Ezinokushisa Okukhulu

•Umklamo Onwetshiwe We-Bonnet Okhipha ImisebeSusa igumbi lokupakisha isiqu kude nezindawo zomzimba ezishisa kakhulu. Amafin okupholisa afudumele akhelwe ngaphakathi avikela izinto zokupakisha isiqu (i-graphite/i-V-ring eguquguqukayo) kanye nama-actuator esandla/azenzakalelayo ekushiseni kombhobho okhanyayo, okuqinisekisa impilo yenkonzo ende.
•Amasethi Okupakisha eBelleville Alayishwe BukhomaUkwanda nokuncipha kokushisa kungabangela ukukhululeka kokupakisha.

•Ukukhululeka Kokukhuliswa Kokushisa NokuzihlanzaIzihlalo zensimbi zinezikhuthazi-mandla zesipilingi ezisindayo ezimunca ukwanda kokushisa okubangelwa uketshezi ngaphandle kokubopha ibhola. Umklamo we-acute-edged scraper sula ama-particulate buildup ebusweni bebhola ngesikhathi sokujikeleza kwekota.
•Izimbozo Eziqinile Ze-HVOF EzithuthukisiweUbuchwepheshe be-High-Velocity Oxygen-Fuel (HVOF) busebenzisa i-Tungsten Carbide noma i-Chrome Carbide ebholeni nasezindongeni zezihlalo ezinamandla okubopha angaphezu kuka-10,000 PSI, okufinyelela ubulukhuni obuncane obufika ku-HRC 70 ukuze kuvinjwe ukuklwebheka okukhulu.

5. Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa Ngobunjiniyela)

Q1: Lingakanani izinga lokushisa lokusebenza eliphezulu lama-valve ebhola ahleli e-PPL uma kuqhathaniswa nama-valve ebhola ahleli ensimbi?

Izihlalo ze-PPL (Polyparaphenylene) zisebenza ngokwethembeka kuze kufike ku-280°C–300°C (536°F–572°F) ukuze kutholakale uketshezi oluhlanzekile kanye nomusi. Amavalvu ebhola afakwe ngensimbi ane-HVOF hardfacing (i-Tungsten Carbide, i-Chrome Carbide, noma i-Stellite) enzelwe izinsizakalo ezisezingeni eliphezulu kuze kufike ku-550°C–650°C (1022°F–1202°F) kanye nemidiya yokuhudula.

Umbuzo 2: Kungani kudingeka ibhonethi ende yama-valve ebhola ashisa kakhulu?

Ibhonethi ende isusa ibhokisi lokupakisha isiqu emzimbeni wombhobho oshisayo, iqeda ukushisa okukhulu. Lokhu kugcina izivalo zesiqu (njenge-graphite eguquguqukayo) zingaphakathi kwebanga lazo lokushisa lokusebenza eliphephile, kuvimbela ukuwohloka kokushisa, futhi kuvikela ama-actuator kagesi noma omoya ekushiseni ngokweqile.

Q3: Ukuvimbela kanjani ukukhiya/ukugabha ibhola emazingeni okushisa aphezulu?

Ukwandiswa kokushisa kulawulwa ngokukhetha izinto ezihlukile ngokunemba (ukufanisa ama-coefficients okwanda kokushisa komzimba, ibhola, kanye nesiqu) kanye nokufaka iziniki-mandla zentwasahlobo ezigcwele bukhoma ngemuva kwezindandatho zesihlalo. Lezi zintwasahlobo ziyacindezela ukuze zimunce ukwanda kokushisa okuphezulu ngaphandle kokwandisa i-torque yokusebenza noma ukubangela ukubopha komshini.

Okwedlule: I-valve yebhola engu-1 intshi
